Belle Composite rollers by Belle Banne Conveyor Products are the next generation in conveyor rollers designed to provide high performance and durability, whilst weighing up to 60% less than conventional steel rollers.
Combining cutting edge polymer technology has led to the introduction of the Belle Composite range of conveyor rollers.
Unlike other Composite rollers, Belle Composite Rollers are available in a range of materials including Nylon, HDPE, and the new FRZ material approved for use in underground applications.
Why Choose Belle Composites?
| PROBLEM | OUTCOME | BELLE SOLUTION |
|---|---|---|
| Corrosion | Exposed steel continually oxidizes. Rust on rolls causes premature failure resulting in costly downtime and under utilised components. | Composite materials designed specifically to cope with corrosive environments |
| Abrasion | Abrasive materials along with corrosive action causes premature wear and failure of the shell | Composite material range designed to offer superior resistance to steel and other composite materials (Sand / Slurry Tests) |
| Weight | Increased on site work injuries, high worker’s compensation claims. Increased fatigue as a result of carrying heavy steel rolls. Increased cost of spares due to poor maintenance, belt downtime. | Up to 60% weight reduction over comparable steel rollers. Ability to safely carry multiple rolls. No specific equipment required for larger roll installations. |
| Safety | Work related injuries as a result of heavy lifting and more time on the conveyor. | Composite materials make overall weight of roll considerably lighter. Hollow shaft technology can further reduce overall weight of a roll. Large diameter stationary rock shield offers barrier to spillage that may trap roll movement and abrade bearing housing. |
| Sealing | Premature roll failure due to ingress of moisture and dust into the bearing. | Sealing arrangements to suit your specific application (moisture/dust). Industry leading seal designs. Independently tested. |
| Increased Power Requirements | Design requirements increase to handle roll performance specifications.(Breakaway mass and Seal Drag) Costs associated with operating a conveyor dramatically increase. | Low breakaway mass and running friction numbers, without sacrificing seal/roll performance. Power required to drive system can be reduced by up to 30% per system. Immediate cost savings. Lower your site carbon footprint today with Belle Composite Rollers |
| Fire Resistance Compliance | Many Composite rollers are not Fire Retardent meaning underground applications cannot take advantage of weight reductions | FRAS roller meets Australian standards for Anti-Static and Flame Retardancy use in Underground Mines. |
| Anti-Static Compliance | Other Composites are unsuitable for use underground. | FRAS roller meets Australian standards for Anti-Static and Flame Retardancy use in Underground Mines. |
| Noise Pollution | Costly citations due to elevated noise emmissions. Failing componentry sound emissions not audible. | Rolls on average +/-10dB lower than steel rolls. Implies up to 90% quieter than steel. Lower noise emmissions allow for improved problem identification as well as a safer working environment. |
| Toxicity Levels | Fatal results due to inhalation of toxic fumes. Particularly relevant to confined working areas. |
Rolls designed using non lethal composite materials. |
| Chemical Resistance | Premature roll failure due to chemical attack to the composite material. | Belle’s range of proprietary materials means we have rolls for various applications, such as sulphuric acid applications (HDPE) |
| Design Flaws | Steel rolls have inconsistent scale quality. Other brand Composites have difficulty achieving strenght on wider widths | Belle materials offer no design restrictions for length and load requirements. No sections welded together. Rolls manufactured very tight tolerances. TIR of less than 0.3mm |
